My ancient Violux printing lamp died on me this week. I've been looking for
a replacement and I've been reading Sandy King's excellent rundown on UV
sources at I'm interested in the HID Metal Halide and
Mercury Vapor lamps, but I'm concerned about lengthy exposures. Does
anybody here use of these? Any ideas on how long of an exposure I might
need with the bulb far enough away to cast a 40" circle of light?
